Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have been informed by my garage that the timing chain tensioner is faulty and needs to be replaced. They say it is a known issue and I am wondering why this has not been made a recall. It is $2,000 and there are no warning signs; it could happen at any time. I don't want to be writing in after a catastrophe so I am writing preemptively: please make this a recall!!!”
NHTSA complaint #11075975, filed 2018-03, 55,000 miles“In the beginning of the week I noticed some unusual behavior with my car, whenever I slowed down to make a turn or to pull up in a garage I felt the car loosing power as if it was about to go off, I will then have to press on the accelerator to give it power and keep it going which was not the safest, knowing that I should be decelerating in such instances. I didn't think much of it, and then 3 days later after parking in a school parking lot for about 12 minutes, I returned to my car to find it not starting up. It will begin to crank but never started. …”
NHTSA complaint #11191567, filed 2019-03, 115,000 miles“While driving my car (2010 Audi A5), the vehicle began to sputter and was not able to drive the vehicle on a state highway. The vehicle would not accelerate and had to pull to the shoulder. It was later towed to Audi of new orleans where I later found out that my car needed a new turbo, timing chain, and timing chain tensioner at a cost just over $4300. After doing research I learned that this is very common with the type of engine that I have. It seems that it occurs in the 2.0t Audi/vw around approximately 80k miles. My car had just turned over 80k. …”
NHTSA complaint #11072850, filed 2018-02, 80,300 miles“I bought the car used and within the first month of purchase and to start putting an additional 1qt of oil on every 1000 miles...now few mints later I have to do that more often on every 500miles... And recently I had to add cooling and now this has been an new issue... My mechanic told me this is a common issue for my car and he is surprised Audi hasn't done a recall on it. My car is under 90k and may require an engine change for over $3-4k. That's not right!”
